[origin: US2017067843A1] A device for monitoring an underground formation containing a fluid such as CO2 or methane comprising a measuring cell (CM) arranged in a cavity, analysis means (MA) arranged on the surface and sealed connection means (ML) connecting measuring cell (CM) to analysis means (MA). The measuring cell comprises two chambers (CH1, CH2) that can sealingly communicate with one another. The First chamber (CH1) comprises a plurality of orifices (OR) allowing passage of the fluid into first chamber (CH1), at least two inner electrodes (EI) and fluid circulation means (MC). Second chamber (CH2) is impervious to the fluid.
